“What I am is determined, determined to stand up for New Jersey. That’s what I get paid for and that’s what I’m going to do whether it’s with Mayor Bloomberg or anybody else,” Christie said on Thursday.

Christie came to blows with the mayor over his refusal to invite former Gov. Donald DiFrancesco — the leader of New Jersey the day terrorists destroyed the World Trade Center — to next month’s ceremonies at ground zero. A New York City newspaper also reported that Christie called Bloomberg a dictator, Napoleon, and a “putz” (the Yiddish curse word that literally refers to a gentleman’s appendage).

“If we allowed New York to make every one of these decisions with just New York no one from New Jersey would be there,” Christie said.

With former Gov. George Pataki invited to participate, along with presidents George W. Bush and Barack Obama, and former Mayor Rudy Giuliani, Bloomberg was forced to relent and ask DiFrancesco, who by the way has never been invited to past anniversary ceremonies — ever.

“I’ve made it very clear to the mayor’s office — I don’t know whether I have to send his business card — but David Sampson is the chairman of the Port Authority of New York and New Jersey. He is the leader of the ground we will be standing on,” Christie said.

But having given in on DiFrancesco, the mayor was in no mood to rent on Samson, too.

“Gov. Christie has not called me and he’s not a shrinking violet. If he had something to say, I’m sure he’d pick up the phone. But you know, when it comes to 9/11, I don’t think the public is interested in some of these made-up stories about political squabbling that really take away from the solemnity – if that’s the right word — of the occasion,” Bloomberg said. “We’ve tried every year to keep the focus not on politics and politicians but on families.”
